If you’re interested in physical fitness, you’ve probably heard of the ketogenic diet. It’s a diet where you eat lots of fat to encourage your body to burn even more fat. In this Purefit Keto review, we’ll be reviewing a supplement that helps your body to do that.
Here’s how the ketogenic diet works to begin with.
In our bodies’ normal metabolic state, we burn carbohydrates for energy. They’re our bodies’ favorite food. Just like a hungry kid will always choose a candy bar over a healthy meal, your body will burn carbs before anything else. The only way to change this is by removing carbs from your diet.
In that case, our bodies have a backup system called “ketosis”. When your body is in ketosis, your liver is converting dietary fat into fatty acids called “ketones”. The idea behind the ketogenic diet is that by training your body to burn fat instead of carbs, you’ll burn more body fat than you otherwise would.
The ketogenic diet is also used to treat epilepsy. For whatever reason – scientists aren’t sure why – the brain cells that misfire in an epileptic seizure function normally when your body feeds them ketones instead of carbohydrates.
Let’s take a look at what Purefit Keto does to help.
What is Purefit Keto?
Purefit Keto is a dietary supplement that comes in a 30-capsule jar, which is a 30-day supply. Each capsule supplies 800mg of exogenous ketones, including Calcium BHB, Sodium BHB, and Magnesium BHB.
We’ll take a closer look at the ingredients in a minute. For now, let’s focus on what Purefit claims to do.
To begin with, they claim that their supplement will trigger ketosis quickly when you take it. The idea here is to give your body a big dose of ketones to kick start your liver, while providing you with an immediate energy boost. This quick boost is particularly helpful for getting into ketosis in the first place, which is why a lot of ketogenic diet guides recommend taking exogenous ketones when you’re first getting started.
They also claim that Purefit Keto is a unique, proprietary formula that’s a technological breakthrough, and that you can lose a pound of fat per day. This is not entirely accurate. While people often shed a few pounds of water weight when they’re starting a ketogenic diet, that only continues for a few days.
After that, a pound a day seems like an extremely high target unless you’re morbidly obese to begin with. We can prove this with basic math. A pound of human body fat contains 3,500 calories, while the average American adult burns about 2,000-2,500 calories per day.
Even if they literally starved themselves, most people wouldn’t lose a full pound of fat every day. Since you still need to eat food to get vitamins, minerals and protein, 1-2 pounds a week is more reasonable for most people.
Purefit has plenty of reason to claim that their product will help you lose weight. Most dieticians agree that ketones help with this. It’s just that the pound a day claim is really only true for people who are extremely obese or who get a lot of exercise.
Purefit Keto Ingredients
So what’s inside these little capsules? Let’s take a look at the label:
- Magnesium BHB, Calcium BHB, and Sodium BHB – We’ve already mentioned these, since they’re the active ingredients. BHB is short for Beta-Hydroxybutyrate, which is one of the three ketones that the body produces naturally when breaking down fats. The others are Acetone and Acetoacetate.
Acetone is unhealthy, is produced in small amounts, and is generally expelled through the lungs. Acetoacetate is produced in larger amounts, but isn’t as plentiful as BHB. As a matter of fact, your liver ultimately breaks it down into BHB before your body can use it. BHB is by far the most common ketone in the body.
So what’s with the Calcium, Magnesium and Sodium varieties? These are simply salts that attach to the ketone to help your body absorb it. Once they enter your blood stream, the salts separate from the ketones, and you end up raising your ketone and electrolyte levels.
Purefit’s claim of a “proprietary formula” probably refers to the mixture of Calcium, Magnesium and Sodium BHB rather than simply relying on one of them. There’s no evidence that mixing different varieties helps you burn more fat, so at most you may benefit from a better electrolyte balance.
- Magnesium stearate – This ingredient is just a filler. It’s biologically inert, so a lot of pharmaceutical and supplement companies add it to their pills for bulk. It doesn’t help the supplement work any better, but it doesn’t hurt anything, either.
- Rice flour – This is another filler, added for bulk. Just like Magnesium stearate, it’s a common additive in supplements. Rice flour is considered healthier than wheat flour because it’s gluten-free and higher in protein.
- Silicon dioxide – Silicon dioxide is an anti-clumping additive. Basically, it keeps the other ingredients from clumping up and losing effectiveness. It’s commonly used in pharmaceuticals and supplements, and is biologically inert.
- Gelatin – Gelatin is used to create the actual capsule. It’s easy to digest, and has no effect on the effectiveness of the product.
Basically, Purefit Keto breaks down like most supplements; a few active ingredients, some inert ingredients, and a capsule.
How Does Purefit Keto Work?
From the ingredients list, we can see that Purefit Keto provides a large quantity of BHB ketones attached to three different electrolytes. So what does that mean for people who are considering a ketogenic diet?
We’ve put it to the test, and it undeniably raises your blood ketone level. As we mentioned, it’s especially useful for getting into ketosis. However, it’s only as good as the rest of your diet. Just like you can’t eat McDonald’s every day and expect to stay healthy with a multivitamin, your entire diet needs to be ketogenic for you to get into ketosis.
That’s not to say that it has no benefits when taken on its own. Ketones do seem to help with mental sharpness, for example, even if you’re not in ketosis.
We didn’t want to limit ourselves to personal experience, so we read a lot of online reviews in fitness forums and other websites. Here’s what we found.
First, there were lots of people who lost weight by combining Purefit Keto with a ketogenic diet and exercise. A lot of people also said that it helped during the first few days, when “keto flu” can cause exhaustion, headaches and mental fog.
This makes sense. When you first go on a ketogenic diet, your liver takes a few days to ramp up ketone production, so you’re essentially starving. By taking exogenous ketones, you’re giving your body energy without feeding it any carbs and undermining your diet.
We also found that some people found it helpful for cheat days. Hey, nobody’s perfect, and going carb free is a difficult lifestyle. If you end up eating a slice of cake at an office party, taking some ketone pills can keep you from going out of ketosis for more than a few hours, and ease any symptoms of carb withdrawal.
Finally, it seemed like a lot of the negative reviews came from people who didn’t change their diet or exercise habits. It seemed like these people were expecting something like a prescription diet pill. This isn’t Purefit’s fault. In their instructions on their website, they specifically say that you need diet and exercise to lose weight.
Is it Effective, or is Purefit Keto a Scam?
Purefit Keto is as effective as you want it to be. We’re not sure where all the “scam” rumors come from – maybe jealous competitors? – but exogenous ketones have been part of the ketogenic lifestyle for years. Taking these pills will raise your blood ketone level. Period.
Admittedly, Purefit’s marketing looks pretty glitzy, which sets off a lot of people’s spider senses. This is particularly true when they make strong claims like one pound of weight loss per day, or use phrases like “proprietary formula”. If they’d just advertised that this is exogenous BHB, there’d probably be fewer people screaming “scam!”. Then again, they might not be making millions of dollars in sales, either.
One common complaint people have is getting automatically billed for additional bottles. This is due to some confusion with Purefit’s site. While they still offer a wide variety of packages, they used to offer a subscription option. This was never mandatory, but some people seem to have been confused and accidentally purchased a subscription instead of buying a single bottle.
Yes, Purefit Keto is effective. No, it’s not a scam.
Potential Purefit Keto Side Effects
Too much of a good thing isn’t always good. Sometimes it’s worse than nothing at all. Purefit is perfectly safe to take in the recommended dose. However, taking too much of it can cause nausea and upset stomach. But why would anyone want to do that, anyway?
As we’ve mentioned, the first few days on a ketogenic diet can be downright miserable. The most common symptoms are headache, fatigue, dizziness, and mental fog. Keto dieters call this “keto flu” for good reason; it really is like having the flu.
Since Purefit Keto can help ease these symptoms, it’s easy to understand why people would be tempted to increase their dose in an attempt to make the symptoms go away altogether. Not only will that make you nauseous, but it won’t do much more to help your symptoms. The reason is that there are multiple causes for keto flu, and not all of them can be fixed by boosting your blood ketone level.
Let’s take a look at a few of the most common causes, and how to manage them.
❗️ Sugar Withdrawal
Carbs are addictive for good reason. They’re the most efficient energy source available, and our ancestors evolved in an environment where carbs were hard to come by. Not only that, the most common source of carbs for prehistoric humans were fruits, which are chock full of vitamins and minerals.
When your body is cut off from its supply of sugar, it freaks out like a junkie in rehab. One thing it does is produce high levels of cortisol, your body’s stress hormone. This is probably the toughest one to deal with, since there’s no cure other than to wait for your sugar cravings to pass.
❗️ Dehydration and Sodium Deficiency
When you go into ketosis, you’ll find that you pee more. Not only can this dehydrate you, it also depletes sodium and other electrolytes which your body needs for healthy function. To mitigate these symptoms, you’ll want to drink plenty of water, and take an electrolyte supplement.
❗️ Caffeine Withdrawal
If you can’t stand the taste of black coffee, you may have cut caffeine out of your diet when you went ketogenic. Congratulations for eliminating sugar! Unfortunately, caffeine is also addictive, and symptoms of withdrawal include exhaustion and headaches.
Fortunately, there’s no reason to eliminate coffee from your diet. You can make a bulletproof coffee by mixing butter, heavy cream, and coconut or MCT oil into your coffee. Make sure to use a blender so the oils don’t all rise to the top.
You can also use a keto-friendly sweetener like Swerve. Make sure the sweetener is keto-friendly, though, not just sugar-free. Most sugar-free sweeteners will still raise your glycemic index.
❗️ Not Eating Enough
A lot of people start restricting calories when they first go on the keto diet. This makes intuitive sense, especially if you’re trying to lose weight.
Here’s the thing: your body is already under a lot of stress learning to live without carbs. Asking it to get by on fewer calories at the same time is only going to add to that stress. Most ketogenic diet guides recommend eating as much as you want for the first week or two. Once your body is producing its own ketones, you can start reducing your calorie intake.
Was the Purefit Keto Shark Tank Ad Real?
This actually caused some controversy early in Purefit Keto’s life. What happened was that an early web advertisement claimed that their product had been funded through the popular TV show Shark Tank. So was it?
No, it wasn’t. It’s not listed in any of Shark Tank’s episode guides, either on their website or elsewhere. However, the Better Business Bureau does confirm that the ad appeared on Purefit’s website, with an image that came from an unrelated episode of Shark Tank. The BBB also confirms that, as far as they can tell, Purefit Keto was never featured on Shark Tank. We weren’t able to find the offending ads now, because they were – understandably – removed from the web.
This looks like a case of someone on Purefit’s marketing team getting overenthusiastic and exaggerating. It also looks like Purefit did the right thing once someone pointed out their mistake, and removed the ad.
What we have here is a product that works. The supplement market is mostly unregulated, so we’re guessing that all that talk about Purefit being a scam is just bad-mouthing from competitors.
Purefit Keto is an established product with years’ worth of experience to back it up. Judging from the large number of positive reviews out there, it’s definitely an effective supplement for a lot of people who take it.
That’s not to say that this is some kind of miracle weight-loss pill. The only thing that makes you lose weight with no effort is a prescription weight-loss medication. And there are a whole host of reasons you don’t want to go that route.
The age-old question “How do I lose weight?” still has the same answer it always did: diet and exercise. Purefit Keto is just a tool to help you get into ketosis and stay there. If you take Purefit and immediately eat a pint of ice cream, you’re not going to get into ketosis. You’ll just have a lot of ketones in your system in addition to all the sugar. However, when combined with a proper diet, Purefit can give your body the ketone boost it needs.
With all that being said the reviews show that a lot of people are not completely satisfied with this product. As such we recommend the more popular and arguably better product Perfect Keto.
If you are looking for that boost to getting to ketosis faster and smoother we highly recommend checking out our review of Perfect Keto.
